Title: High-frequency amplifier with signal level control means and transmitter with it
Inventor: BERUNTO HAABAARANTO
IPC: H04B7/005
Filed: 1994-04-22
Abstract: PURPOSE: To provide an RF amplifier which controls the level characteristic of RF signals, particularly, TDMA radio signals separated to continuous time slots and is stably controlled. CONSTITUTION: A high-frequency amplifier is provided with a control circuit which evaluates the actual level characteristic of RF signals which are separated to continuous time slots T1(k) and T2(k) in two or more segments GT and AT having preset desired level characteristics at each time interval. The control circuit decides an error by not evaluating the actual level characteristic in the first segment GT in each time slot in which the level characteristic dynamically changes, but by deciding a fixed error value by comparing the desired value of a desired constant level characteristic in the second segment AT with the actual value, and performs level control on the time slot corresponding to the next frame by utilizing the error.

IPC: G11B7/24024
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent warpage of a disk by applying a colored UV-curing resin on the surface of a first transparent substrate where a recording layer is formed and on one surface of a second transparent substrate and then putting these surfaces one upon another. SOLUTION: A UV-curing resin 4 is applied on the surface of a first transparent substrate 2 where a recording layer is formed, and a UV-curing resin 5 is applied on one surface of a second transparent substrate 3. These substrates are laminated, and then hardened and fixed by irradiation of UV rays. By using a colored resin for the resin 5, the UV rays irradiating the substrate 3 is partly reflected or absorbed by the dye, while the UV rays irradiating the substrate 2 is partly reflected or absorbed by the recording layer 1. By controlling the reduced intensity of the light by reflecting or absorption on both sides equal to each other so that the hardening of both resins is the same, a flat laminated disk without warpage can be obtd.  By coloring the resin, 5 even when bubbles 7 are produced between the resin coating layers, bubbles are shielded by the colored layer, and the recording layer 1 so that bubbles are not observed from outside is prepared. Thus, the obtd. optical disk is excellent in appearance.
